About this map

The South Fork Trinity River flows through the heart of the Hyampom Valley, where the small settlement of Hyampom serves as a remote hub within the vast timberlands of Northern California. This 2018 survey detail shows the convergence of the South Fork Trinity River with Hayfork Creek, a vital hydrologic junction near Deadmans Point. The landscape is characterized by its dramatic vertical relief, reaching from the riverbanks up to Limedyke Mtn and South Fork Mtn.

Boundaries between the Trinity National Forest and Six Rivers National Forest meet here, marked by a complex network of forest routes such as St John Rd and Lower South Fork Rd. Small high-elevation water bodies like Maddox Lake and Lily Lake sit perched above the drainage basins of Butter Cr and Johnson Cr, while the presence of Sulphur Spring indicates the area's geothermal diversity. Historic grazing and forestry activity is evidenced by named clearings including Waldorff Flat, Wintoon Flat, and Oak Flat.
